摘　　要：新疆准噶尔盆地西北缘红山嘴地区白垩系清水河组油藏埋藏浅、产量高、剩余出油气井点多,具有高效油藏滚动扩边的潜力。前期由于成藏主控因素认识不清,导致该区评价工作停滞不前。本研究通过重新梳理本区断裂及构造特征,结合重点出油气井测录井资料的分析与研究,深入剖析了不同井之间油气水关系及油气富集规律。研究表明,红山嘴地区油藏受多期砂体叠置及断裂耦合共同控制,形成超覆背景下的断层-地层油气藏,具有“一期一藏、断裂分块”的特征。通过综合研究建立本区“断裂垂向疏导、侧向遮挡分块、地层尖灭控藏”成藏新模式,本文在新模式下明确了H67井区多期超覆尖灭带是最为有利的成藏区带。以上研究成果对该区清水河组油藏储量探明升级及高效建产具有重要的指导意义。The reservoir of the Cretaceous Qingshuihe Formation in the Hongshanzui area on the northwestern margin of Junggar Basin in NW China features shallow burial depth,high yield,and many remaining productive wells,and has the potential for efficient reservoir expansion.However,the main controlling factors remain unclear today,which limited the progress in the evaluation of reservoirs.Based on an analysis of the fault and structural characteristics,and the logging data of key oil and gas wells,the oil-gas-water relationship among different wells and the oil-and-gas enrichment rules were studied in depth.Results show that the reservoirs in the Hongshanzui area are mainly controlled by multi-stage sand bodies and faults,forming fault-strata conformed reservoirs under stratigraphic onlap background in every stage of reservoir evolution in fault-delimited blocks.A new mode for this area was established for petroleum accumulation that is“controlled by faults for vertical diversion and lateral blocking,and by strata pinching out”,by which the area around the center of H67 Well was determined the most favorable petroleum accumulation zone featuring multi-stage onlap and strata pinchout.The above results are of great guiding significance for upgrading the proved reserve in the Qingshuihe Formation and promoting the production capacity buildup in the Hongshanzui area.
